The third part of the Tides of Vengeance content update for World of Warcraft's Battle for Azeroth expansion is here. The update's main attraction is a couple of long-awaited allied races, but apart from that, it also adds some new story content and world quests, visually overhauls two of the game's oldest Battlegrounds, re-introduces the Brawler's Guild, and more. Check out this quick video guide for a detailed overview:

Take the final steps to bring new comrades into your faction. Level 120 players who wish to create a Kul Tiran will need to reach Exalted with Proudmoore Admiralty and earn the achievements A Nation United and Tides of Vengeance. Those wanting to create a Zandalari character must be level 120, reach Exalted with Zandalari Empire and earn the Zandalar Forever! and Tides of Vengeance achievements. Once you complete the requirements, visit the Alliance embassy in Stormwind or Horde embassy in Orgrimmar to begin a quest chain to recruit these new Allied races.

Kul Tiras was founded by fearless explorers who sailed uncharted waters in search of adventure. As a key member of the Alliance of Lordaeron, the Kul Tiran navy dominated the seas of Azeroth with its legendary fleet.

The Zandalari are a proud people whose origins date back to the early days of Azeroth's history. Their fierce warriors ride dinosaurs into battle, and they possess one of the most formidable naval fleets in the known world.

Leveling your new Kul Tiran or Zandalari from 20 to 110 will earn you a unique cosmetic Heritage Armor set. You’ll also unlock a new mount—the Kul Tiran Charger or Zandalari Direhorn—for your collection at character creation.
